I played Poker Night on Steam for several hours, racking up a nice quantity of statistics, unlocks, and the like. I decided to take a break to play TF2 for a bit. The only things I did between closing Poker Night and opening it again were to Play TF2 for about 30 minutes, and log into my Steam Friends list. When I went back, a good portion of my data appears to be missing, as follows:
* The session I was midway through is still there, but with the default table/cards.
* My stats page claims I have never played a hand, and all stats reflect this.
* My stats page indicates I have none of the TF2 unlocks (I have all four).
* When I FIRST switch to the unlocks page, all my unlocks are there until the page loads properly (that is to say, until I regain control of the cursor), at which point none of my unlocks are visible. (I realize this description is a bit unclear, so I added a pair of screenshots: http://imgur.com/qBqun.jpg
This is a bit irksome, since I'm afraid to continue playing the game in the event that it will overwrite my old data, since it's presumably still around in some form. The Steam forums also indicate this isn't an isolated issue, though not nearly as prevalent as the "no graphics" and "can't get it to load at all" bug.
Any assistance or support would be greatly appreciated.
P.S. Already tried verifying the integrity of the game files via Steam, but no dice.
